He left the cell, but presently unlocked the door and pushed his dismal face round the corner. ‘I am Captain Sinclair, of the Duke’s household,’ he said, ‘should you have occasion to ask for me. You had best have spiritual help, for I do assure you that there hath been something worse than either warder or prisoner in this cell.’ ‘What then?’ I asked. ‘Why, marry, nothing less than the Devil,’ he answered, coming in and closing the door. ‘It was in this way,’ he went on, sinking his voice: ‘Two years agone Hector Marot, the highwayman, was shut up in this very Boteler dungeon. I was myself on guard in the corridor that night, and saw the prisoner at ten o’clock sitting on that bed even as you are now. At twelve I had occasion to look in, as my custom is, with the hope of cheering his lonely hours, when lo, he was gone! Yes, you may well stare. Mine eyes had never been off the door, and you can judge what chance there was of his getting through the windows. Walls and floor are both solid stone, which might be solid rock for the thickness. When I entered there was a plaguy smell of brimstone, and the flame of my lanthorn burned blue. Nay, it is no smiling matter. If the Devil did not run away with Hector Marot, pray who did? for sure I am that no angel of grace could come to him as to Peter of old. Perchance the Evil One may desire a second bird out of the same cage, and so I tell you this that you may be on your guard against his assaults.’ ‘Nay, I fear him not,’ I answered. ‘It is well,’ croaked the Captain. ‘Be not cast down!’ His head vanished, and the key turned in the creaking lock. So thick were the walls that I could hear no sound after the door was closed. Save for the sighing of the wind in the branches of the trees outside the narrow window, all was as silent as the grave within the dungeon.
